The resultant SnO2 nanowires possess diameters from 50 to 100 nm and lengths up to tens of mircrometers. The field-effect transistors based on single SnO2 nanowire exhibit that as-synthesized nanowires have better transistor performance in terms of transconductance and on off ratio. This work demonstrates a simple technique to the growth of nanomaterials for application in future nanoelectronic devices. Keywords SnO2 nanowires Semiconducting Field-effect transistor Introduction One-dimensional semiconductor nanowires and nanotubes have stimulated increasing attention in the last few years and are expected to lead to novel device application due to their intriguing properties and potential applications in Z.-J.
